Abstract

Ein erster geschlossener Druckraum (14) wird gegenüber einem zweiten geschlossenen Druckraum (16) abgedichtet, wobei in den Druckräumen (14, 16) unterschiedliche Medien gespeichert sind. Zwischen dem ersten Druckraum (14) und dem zweiten Druckraum (16) ist eine Verbindung über eine Kolbenstange (13) oder eine Welle geschaffen. Die Kolbenstange (13) bzw. die Welle ist beweglich zwischen den Druckräumen (14, 16) gelagert und über eine Dichtungsanordnung (18) abgedichtet. Die Vorspannelemente (23, 24) sind hydraulisch mit dem zweiten Druckraum verbunden.
